Symptoms of 1KD-2KD Engine Injector Ring Set Having Problems

Symptoms of 1KD-2KD Engine Injector Ring Set Having Problems – Having an engine in top condition is a car owner’s dream. Damage that occurs to the engine will result in engine performance being not optimal. Thus, maintenance and sensitivity to any problem anomalies that occur in the engine are the obligations of car owners. We must carry out this obligation absolutely without bargaining.

Small damage that occurs to the engine and slows getting treatment is not impossible and will result in greater damage. If the damage is severe, of course, this will require a very large cost as well. No matter what car breaks down, all cars can experience the same thing. And so are the cars with 1KD and 2KD engines from Toyota.

1KD-2KD Engine

As in the minor damage to the Toyota Diesel engine, namely the 1 KD and 2 KD engines with minor damage, namely the damage to the injector ring set. This damage is normal damage to both types of machines. I say normal because these components have a usage time limit.

1KD-2KD Engine Ring Set Injector Having Problems

Toyota launched the 1KD-FTV engine in 2000. The 1KD-FTV has a 3.0L (2982cc) inline 4 common rail cylinder with a variable geometry turbocharger and Intercooler. Toyota applies this 1KD engine to the Toyota Land Cruiser Prado, 3rd generation Hilux Surf as well as Toyota Fortuner, Hiace, and Toyota Hilux.

Meanwhile, Toyota launched the 2KD engine in 2001. The 2KD-FTV appeared with a smaller cylinder capacity of 2.5 L (2494 cc). This engine capacity is taken from the previous generation, namely the 2L engine. The diameter remains 92 mm but the step becomes 93.8 mm. Toyota has also equipped the 2KD-FTV engine with a turbocharger and intercooler.

This 2KD engine is found in the Toyota Hilux, Toyota Fortuner, Toyota Kijang Innova, and Toyota Hiace. Currently, the 2KD-FTV machine has stopped production. Instead, Toyota issued a machine coded 2GD-FTV.

Symptoms of 1KD-2KD Engine Injector Ring Set Having Problems

The injector ring set on the Toyota 1KD and 2KD diesel engines is made of brass material. Why this material? The goal is to be softer than the injector material itself. One of the characteristics of the 1KD and 2KD engine ring set injectors that must be replaced immediately is the buildup of air pressure in the engine room. Its characteristics are that the air will gush very hard when the engine oil filling cap is opened when the engine is running.

By construction, the head of the top side of the 1KD and 2 KD engine injectors is buried under the valve cover where the oil-filling hole cap is attached.

However, actually, diesel engines have more injector damage symptoms than just the things mentioned above. The following are symptoms of injector damage on common rail engines in general – Symptoms of 1KD-2KD Engine Injector Ring Set Having Problems.

1. Car Engine Difficult to Start

Let’s start with the signs of a damaged car diesel injector that are the easiest for us to recognize. The symptom is that it is difficult to start the engine. Why is it that when a car’s diesel injector breaks down the engine becomes difficult to start? This is because the supply of fuel into the combustion chamber is not smooth. Of course, the fuel that comes out of the injector is not up to standard. Or, it could be that the engine becomes difficult to start because the injector pressure decreases, due to worn or damaged injector conditions.

2. Car Engine Staggered

Then, even though the car has begun to be turned on, generally there will be signs of a damaged car diesel injector next. What’s that? The symptom is none other than the engine becoming choked. This condition is due to the supply of fuel that is not smooth. This, results in a machine whose performance is not stable, aka sometimes it turns on or sometimes it can also turn off by itself

To expedite the supply of fuel, then we have to make adjustments to the injector of the car. In addition, you can also replace the injector if it has a problem.

3. Fuel Inefficient

After the engine feels sluggish or cramped, then in terms of fuel consumption, it becomes inefficient. The meaning of less efficient fuel consumption is when fuel consumption becomes too economical or also too wasteful. This is none other than a problem with the car’s injector.

Wouldn’t fuel economy be good for the car? Fuel efficient but performance remains stable, maybe good for the car. However, in the case of a damaged car diesel injector, fuel consumption that is too economical will actually result in reduced engine power. This fuel economy is due to the injector that cannot open properly when it comes to supplying fuel.

Likewise with wasteful fuel. When you feel the fuel becomes very wasteful, it will result in thick smoke coming out of the exhaust. This is because the composition of the fuel is more than air. That is why combustion is incomplete. The cause of this inefficient fuel intake is that the residual gas from combustion actually becomes crust at the end of the injector. This makes the injector unable to close or open properly.

4. Non-Optimal Performance

The injector serves as a component that serves as a fuel atomizer. If the injector has a problem, then it cannot supply enough fuel into the combustion chamber, and this results in less than optimal engine performance.

In order for the engine to work normally, each engine speed requires a different fuel intake with different capacities. For example, when the engine is in the start process, the engine requires more fuel than at idle which requires less fuel. And if the injector has a problem, then the fuel supply becomes irregular and causes the engine to turn off by itself.

5. Thick smoke comes out of the exhaust

Furthermore, the last sign of a faulty car diesel injector is easy to spot. The release of smoke from the exhaust hole is a sign of the fuel supply is too much. Where it is a sign of a wet combustion process, where the fuel mixture is more than the air. This results in the remaining gas produced turning black.

So, if there is one of the several signs of a damaged car diesel injector above, it’s a good idea to immediately do further checks and services at the workshop.
